Subject: [DTS][PATCH V5 2/4] tests/vf_offload: add vf checksum hw offload case for tunneling packets.
Date: Fri, 23 Dec 2022 11:22:33 +0800 [thread overview]
Message-ID: <20221223032232.412042-3-ke1.xu@intel.com> (raw)
In-Reply-To: <20221223032232.412042-1-ke1.xu@intel.com>
In DPDK 22.11, tunneling packets checksum offload for inner and outer checksum is supported.
This case supporting validation these packets.
